Class DownRoundingAnimationControlJ3D

java.lang.Object

visad.Control

visad.java3d.AVControlJ3D

visad.java3d.AnimationControlJ3D

visad.java3d.DownRoundingAnimationControlJ3D

All Implemented Interfaces:

Serializable, Cloneable, Runnable, AnimationControl, AVControl

public class DownRoundingAnimationControlJ3D
extends AnimationControlJ3D
implements Runnable, AnimationControl

DownRoundingAnimationControlJ3D extends AnimationControlJ3D to provide a different sampling behavior. Instead of nearest neighbor, the nearest sample LESS THAN the current value will be displayed.

Methods

Modifier and Type	Method and Description
protected int	getIndexLessThanValue(Set set, double value) Return the index of the sample with the nearest value less than or equal to the given value, -1 if no earlier samples.
void	init() actually set Switches (Java3D) or VisADSwitches (Java2D) to child nodes corresponding to current ordinal step number
void	selectSwitches(double value, Set animation_set)
void	setCurrent(double value) set the current step by the value of the RealType mapped to Display.Animation
void	setCurrent(int c) set the current ordinal step number = c
